display doesn't use complete viewable area

Specs: Windows 7, Intel i7 920
Hi, I recently got an Acer S243HL 24" monitor and when I use the HDMI connection on the monitor from my ATI 4870 512MB graphics card via a DVI to HDMI dongle using the native resolution of 1920x1080 the image doesn't use the full display area and leaves a 20mm gap all the way round the image. I've downloaded and installed the latest monitor driver from Acer as well as ATI's latest Catalyst driver but just cannot find a way to enlarge the image to fill the screen!

I've been through the monitors confiiguration software as well as through the catalyst software to no avail. :o(

Help please!

Don't overlook the obvious. Did you try the configuration buttons on the monitor itself? LCD monitors typically include the old style buttons that the CRT monitors used that allow you to recenter and resize the screen.

Thanks for the replies! :o)

I've been through the menu and looked at the options but the OSD has very little in it to be honest and the only move options are to move the position of the OSD itself, no options to stretch or shrink the picture :o(

When I use Catalyst to change the res it has two categories of resolution, Basic and HD. If I use a Basic res (goes up to 1680x1050) the full screen is used, but if I use on of the HD res options it goes back to having the black bar round the outside.

I can't see any difference when running catalyst in compatability mode either, an option to resize and move the image is there when using a VGA connection to the monitor but not when using the HDMI lead.

Its really frustrating as its a really nice monitor but I just cannot get it to work properly. Called Acer and they told me it was a software issue and that I had to call their premium 50 pence a minute line to sort it out....

Are you sure that your video card supports HDMI through DVI....Not all of them do. Also are you using the latest drivers for your video card?
Update:
Sorry, I just looked up your card and it does appear to support HDMI through DVI adapter BUT it might only support it through ONE of the two DVI connectors. Try the other connector or check the paperwork that come with it. (and do check for driver update)

Yeah made sure I got the latest Catalyst driver (10.2) and tried connecting to both DVI outputs. I did connect the monitor to my media centre pc which has an HDMI output on it and that displayed correctly, whereas the other halfs PC had the same issue as mine and she has a 4870 too, albeit from a different manufacturer and more memory on board but fundamentally the same card. Looks like it might be an issue for the 4870's which is gutting. Looking at getting a 5850 as that has an HDMI output on it so no need for an adaptor...

Should be an overscan trouble (for me it works !) Go to ati catalyst find the overscan option set it to 0% and it's done

Hello there! Here is the solution to your problem: open the
catalyst(TM) control center in advanced mode.

Then go to Desktops & Displays.

You'll find two schematics of your screen, with a small black
triangle in the upper left corner, one schematic in the middle
of the window, and another small one below. Click on the
triangle on the schematic below, and go under "configure".

The solution is then under "scaling options", where you can
modifiy the scaling of your screen. The best mode is 0% in
1920x1080.

Hope it helps, it did for me!

Greetings.
